Fisher Scientific Isotemp 500 LCSU Recirculating Chiller

The Fisher Scientific Isotemp 500 LC Recirculating Chiller is new. This chiller has a full range of heating and cooling from -10°C to +80°C with fast ramping time. The intuitive user interface allows users to choose between five temperature setpoints. With a small footprint and quiet operation, the Isotemp 500 LCSU is ideal for any lab environment.

Applications include chemical reaction control, separations, life science instrumentation, mass spectroscopy, molecular spectroscopy, atomic spectroscopy, surface science, materials characterization, laboratory automation, and general laboratory instrumentation.

This chiller is in new condition and is fully tested to perform at factory specifications before being shipped.

Recirculating Chiller Inspection and Recertification Checklist

• Inspect display for dimming or dead pixels and replace as necessary to maintain clear visual feedback
• Verify functionality of all buttons and input devices, ensuring reliable and responsive control
• Check that all external hosing connections are secure and properly installed to prevent leakage
• Test unit flow rate on a closed-loop system to confirm consistent fluid dynamics
• Examine all external surfaces for leaks, confirming a sealed and contained system
• Inspect internal components for any signs of leaks to ensure system integrity
• Verify power supply output for accurate voltage delivery per operational specifications
• Inspect all internal wiring, checking for any frays, tears, or compromised insulation
• Replace internal filters to maintain optimal fluid purity and system performance
• Confirm that the fan operates at proper speeds to provide effective cooling
• Verify compressor functionality for consistent performance and cooling efficiency
• Test cooling capacity, confirming it meets performance specifications at 20°C
• Measure water pump output to confirm correct PSI for stable fluid flow
• Determine the lowest achievable temperature, verifying against manufacturer standards
• Ensure cosmetic condition meets standards with no damage affecting functionality or aesthetics
